Polarized light detection plays an important role in remote sensing, near-field imaging, communication, and high resolution detectors. However, it remains a great challenge to achieve highly polarization-sensitive photodetection with large polarization ratio base on traditional semiconducting materials due to the limitation of material/device structural anisotropy.

Ferroelectric materials, characterized by switchable electric polarization, inherently feature a highly light-polarization dependent photoresponse (known as bulk photovoltaic effect, BPVE), presenting as promising alternatives in this portfolio.
